Detailed Description of the Invention [Field of Industrial Application] This invention relates to a pressure distribution measuring rubber plate used in a measuring device that quantitatively measures the distribution state of blood pressure. .

ストであることから重視されている。Conventionally, methods for measuring the distribution of surface pressure include a method of distributing a large number of load detectors on a bar surface and a method of measuring the electrical conductivity of a pressure-sensitive rubber. The improvement method () is to use a capacitance method to measure blood pressure distribution, which can reduce the variation in characteristics depending on the measurement location, has good reproducibility of measurement, and has a straight line ↑ No. 1. It is valued for its good performance, low hysteresis, and low cost.

る。The outline of this capacitance method for measuring pressure is as follows: Spring materials (cushion, sponge, Amat, etc.) made of appropriately selected insulating materials, polymer phase, paper, LLI cloth, glass, etc. ) is sandwiched between two shielded electrode plates on both sides.A high-frequency signal is applied to one of the electrode plates, and a spring material is sandwiched between them. The high frequency signal that passes through and is transmitted to the other electrode plate is heterodyned (h

ものである。The basic structure of this sensor section consists of a shield layer from the outside,
It has a structure in which a spring material (insulator) is sandwiched from both sides by layers consisting of an insulating layer, an electrode layer, and a polyester film, and when a load W is applied perpendicularly to this layer, the thickness of the spring sheath t ta The magnitude of the load The output of the heterodyne detector is obtained as a function of the load W. Conventionally, pressurized conductive rubber or a rubber plate with good elasticity has been used for this spring material, and both have adopted a simple flat plate shape. Furthermore, for pressure distribution measurement using pressure-sensitive paper, a rubber plate having conical or chevron-shaped protrusions has been used.

じ単位面積当りの力を加えても、ゴムの変形量が異なり
測定値は正確でない値を示すことになる。None of the conventionally used rubber plate shapes described above allow accurate measurement of surface juice. This is because the amount of deformation due to pressure on a pressure-sensitive part changes depending on the shape factor of that part, so even if the same force per unit area is applied when the pressurized area is wide or narrow, the rubber deforms. The quantities will be different and the measured value will show an inaccurate value.

る。The goal is to solve the problem of the shape of the rubber plate so that the pressure per unit area and the amount of rubber deformation can always be determined correctly, and to greatly improve the accuracy of measurements. Note that the shape factor is the pressure-receiving area divided by the free area, and is one of the indicators of the ease with which the rubber plate deforms. For example, in a square prism, if one side of the square is a, the pressure receiving area is a2, and if the height of the square prism is b, the free area is 4ab.
It is displayed as a. Therefore, the shape factor is -Issho Hyakkoku -4b.

。As mentioned above, the shape of the rubber plate of the pressure sensitive part, the required shape factor formed by a certain pressure receiving area and a certain free area are the primary matters for solving the problem. The objective is to use materials with low hysteresis loss, low aging resistance, and low fatigue resistance.

ある。The present invention, which eliminates the above-mentioned drawbacks of the conventional technology, uses a rubber with a small hysteresis loss, for example, a rubber with an inorganic filler content of 10%.
By using peroxide-cured natural rubber or silicone rubber with a ratio of 50 parts or less of rubber to 0 parts, it improves measurement reproducibility, linearity by 1 point, and response speed by 1 point, while improving sensitivity. By making each pressure part independently separated at least in part by surrounding grooves, the relationship between pressure and strain on each pressure sensitive part can be adjusted to the distribution of surrounding pressure. In other words, the groove 61 rubber plate forms the required shape factor in which the pressure sensitive part is recessed by 1 in the surrounding groove. In this method, a pressure sensitive part formed independently on the inner side of the rubber plate by a peripheral groove is used as a pressure measuring part.

The relationship between the pressure and strain of each pressure-sensitive part becomes constant, and the 8th
It has been found that no error occurs between the curve 8 and the curve shown in the figure. This is because, in Figure 7-1), even if the pressure-receiving area and free area of each pressure-sensitive part (in the figure, the lateral area of the pressure-sensitive part) are constant, the relationship between pressure and strain is always constant, Figure 7-(a) and Figure 7-(
